MACHINE FOR TRE'ATING LEAF-TOBACCO.

SPECIFICATION forming part of Letters Patent No. 330,734, dated November17, 1885.

Application filed July 20, 1865. Serial No. 172,097.

.To all whom it may concern:

Be it known that I, JOHN A. PoIsT, of Mc- Sherrystown, in the county ofAdams and State 0f Pennsylvania, have invented certain new and usefulImprovements in Machines for Treating Leaf-Tobacco, of which thefollowing is a specification, reference bei-ng had to the accompanyingdrawings, and to the letters of reference marked thereon.

This invention has reference to a machine designed for preparingleaf-tobacco for cigarmaking; and it consists in devices whereby theleaf is stripped and loooked,77 and the veins of the leaf flattened out,so that when the leaf is used for cigar-wrappers, the eXterior surfaceof the leaf shall be found smooth and even. By booking7-which is a termtechnically used by cigar-makers-is meant the removal of the wrinkles orunevennesses of the leaf. This cannot be effectually accomplished byhand, and one of the objects of my invention is to effect in anefficient manner what heretofore has been imperfectly effected by hand.

In the accompanying drawings, Figure l is a perspective view of themachine. Fig. 2 is a view showing the under side of the machine. Figs. 3and 4 show details.

Similar letters of reference indicate similar parts in the respectivefigures.

A is the frame of the machine, which, as shown in Fig. 2, consists ofthe side pieces, a, and the end pieces, b, suitably attached together.

B isa shaft or mandrel mounted in bearings c, placed upon the sidepieces, a. The bearings may be of any suitable form, and are ar rangedto take up the Wear ofthe journals in the usual manner. Upon the shaft Bis placed a roller, C, preferably in two sections and of iron, and atthe center of the shaft are placed two knives, D D, of thin sheet-steel,having sharpened edges. The construction is such that the roller andknives are fixed upon the Shaft B against revolution, the shaftrevolving in its bearings. I do not confine myself to the constructionof the shaft and roller or their arrangement with respect to each other,as they may be variously modified.

E is a table,which is of a width equal to the (No model.)

distance between the side pieces, a a, of the frame, and which tablerests under the roller G. The table is provided centrally andlongitudinally with two slits, d, of a width about equal to thethickness of the metal of which the knives D are formed. The top or topand bottom of the table may be covered with plateiron. The knives D are'placed a short distance apart, as shown, the distance being equal tothat of the width of the cut intended to be made in the leaf for theremoval of the stem. The collar c between the knives is preferablyrubber-coated or milled upon its outer edge, to give it increasedfrictional hold V.upon the removed stem to carry or draw it ranged torun freely betweenV the upper and the lower rollers.

The operation is as follows: The leaf of tobacco, having been suitablymoistened in the usual manner, is placed lengthwise and centrally uponthe slidingtable E, and the table is then pushed forward by theoperator, the leaf being caught under the rollers C and the knives D,which extend below-the upper surface of the table. The stemis thusremoved. The effect of the rollers C is to straighten out or book theleaf in a more effectual manner than has heretofore been accomplished byhand.

It is found that tobacco treated in the foregoing manner retains itslevel orv dat state, not assuming its wrinkled or uneven condition. Theveins of the leaf are also flattened out, so that when the leaf is usedfor a cigar-wrapper the veins are practically level with the generalsurface of the cigar.

The upper and lower rollers may,if desired, be made adjustable, so as toincrease or decrease the pressure upon the leaf, and for this ICOpurpose the adjusting screws and nuts c, as 2..The combination of therollers C C', 1o

shown in Fig. 4, are used. v knives D, collar c', and slitted table E,for the Having described my invention, I olairnpurposes speeied. l.
